摘要
为制备高效煤炭微生物絮凝剂,论述了煤炭微生物絮凝剂的物质组成及絮凝效果,重点讨论了微生物絮凝剂的引入分形理论改良絮凝动力学的研究进展,分析了絮凝剂投加机制和絮凝剂微生物对煤炭微生物絮凝效果的影响。针对目前煤炭微生物絮凝剂存在的问题和局限,提出了展望。未来应加强煤炭微生物絮凝活性物质结构的研究,特别是分子层次的研究;从基因调控,DNA诱变的角度开展煤炭絮凝微生物的选育工作,以生物工程的方式组建高效工程菌;加强煤炭絮凝微生物的复合菌型技术研究以及微生物絮凝剂与传统絮凝剂的复配效果研究,探索多种协同复配的给药制度。
In order to prepare kinds of coal microbial flocculants with good performance,the component and flocculation effects of coal microbial flocculant were introduced. The research progress of flocculant kinetics improvement by adopting fractal theory was investigated. The effects of dosing methods and microbe on flocculation were analyzed. The structure of active substances of coal microbial flocculant on a molecular level was the emphasis of research. More biological engineering methods should be introduced to raise microbe. The raising of coal microbial flocculant should consider gene regulation and DNA mutagenesis. The raising of compound microbe and the synergistic effect of microbial flocculant and traditional flocculant were the emphasis of research.
